People needs to be energetic because we need to have energy in our body.And eventhough we eat foods that are not really nutricious we will stay the same as what we are before.
The leftover energy gets stored.Love,Justin Bieber :)
We need food and sleep
No, biomass typically produces energy through incineration which does not require solar energy.

Turn the lights when ever you don't need them save energy people
If people could generate their own energy, they would never need to eat, as they would no longer need the energy from outside food sources.
So we can get energy and stamina.
A windmill produced electricity while the wind blows. It may produce energy when the wind blows and people don't need it. People don't need all the energy a windmill produces all the time but they may need energy when the wind is not blowing. Windmills are therefore linked up to battery systems and charge the batteries when the wind is blowing, energy is being produced, and nobody is using it. When people need energy and the wind is not blowing (no power is being produced) they use power from the batteries.
More population = more people who need energy = higher total energy requirements.
they need energy so they can live and feel healthy

To live, to get energy and to be healthy
to renew the energy - to reuse it. that's why it will never run out. but more people need to start renewing energy otherwise the energy will run out
Spaghetti is a pure source of carbohydrates, and people need carbohydrates for energy.
if we don't have energy, we will not be able to carry on with our activites that we do. For example if your running 400m, you will need to energy to be able to carry on the run. You will need to drink lots of water before the run and eat a healthy meal to give you extra energy.
one reason people need food is because we need energy to get through the day
